I wanted to add these diagrams to help others not spend as much time as I did to figure it out. this is working in my vehicle with this setup.
Step1
what makes the gauges work. I soldered 2 metal leads that came off of capacitors and inserted them into my obd port at these 2 locations. I tried to get them in the backside but they came lose after remounting the obd port. so sticking in the front is working and easily removed if needed.
step2
this is what interfaces with your steering wheel controls
step 3
getting the remaining wires connected for specific to installing the maestro unit the 2 wires from connector g are what gets power to the unit. the other items are specific to a pioneer head units setup so please check you head unit to make sure they are the same..
Also if your system has factory Bluetooth you will not be able to get the factory usb and auxiliary to work with a new head unit do your self a favor and order a new one usb and auxiliary port with 6ft cable and 2 harnesses so you can pull cables and pins from one to add the one you will use or be prepared to make your own or splicing the vehicle sire on off and wiring everything directly. Good luck
A few extra items found on the interwebs that can help make sense of this.
